| 摘 要： | 分析松突圆蚧在松林不同梢位间的扩散与分布可知:松突圆蚧于9~10月从秋梢向春梢扩散,9月中旬开始,10月下旬为扩散高峰期;于3~5月从春梢向秋梢扩散,5月上旬和下旬是扩散高峰期。9~12月期间,旧梢上松突圆蚧虫口总数呈缓慢下降的趋势,新梢上虫口总数则快速增长;自新梢有虫为害始,约经过105 d,种群数量达到旧梢上的水平。

| Abstract: | By means of spot survey in Fuqing, Fujian Province from 2003 to 2004, the results showed that the initial and important stage of Hemiberlesia pitysophila spreading to spring tips from autumn tips of pine was Sept. and Oct. , and.the stage of the pests spreading from spring tips to autumn tips was March, April and May. The pests began spreading to spring tips in the middle ten-day of Sept. , and the last ten-day of Oct. was the fastigium. Moreover, the pests began spreading to autumn tips in the last ten-day of April, and the first and last ten-day of May was the fastigium. In the period from Sept. to Dec. , number of the pest population on the old tips declined tardily, but that on the new tips increased rapidly. As a whole, number of the pest population on the new tips reached the level of the old tips by 105 days development after the first time of the new tips attacked by the pest. |
